With increasing **material complexity**, **frequent color changes**, and **tight production schedules**, **an ineffective purging process leads to unnecessary scrap, downtime, and quality issues**. The solution? **A strategic purging program.** **This blog covers:** ✔ Why top-tier automotive suppliers rely on purging compounds ✔ How the right purge process reduces scrap and boosts machine efficiency ✔ The real cost of NOT having an optimized purge program --- ## **1. Meeting Stringent OEM Requirements** **OEMs expect flawless, contamination-free parts.** A **single defect** can result in **rejected shipments, costly rework, or lost contracts**—all of which impact your bottom line. ✅ **Why Purging Matters:** - Eliminates **material contamination** to prevent defective parts - Ensures **consistent production quality** to meet **OEM specifications** - Reduces **color streaking and carbon buildup**, keeping your parts pristine 💡 **Example:** An injection molder working with an EV manufacturer cut their contamination-related rejects by **37%** after switching to a high-performance purging compound. --- ## **2. Ensuring Reliable, High-Quality Production** 🔴 **A single bad part can mean a recall.** 🔴 **Machine downtime means lost revenue.** In an industry where **precision, safety, and consistency** are critical, automotive manufacturers can’t afford machine inefficiencies. **How an Effective Purging Program Improves Production:** ✔ Eliminates **black specks, streaks, and color contamination** ✔ Extends **screw and barrel lifespan** by preventing excessive buildup ✔ Reduces **machine wear**, ensuring reliable and long-lasting performance 📉 **Results:** Automotive manufacturers using Asaclean® see an average of **44% reduction in scrap and downtime**—directly improving profitability. --- ## **3. Reducing Machine Changeover Downtime** 🚗 **The Problem:** Frequent color and material changes slow down production. As vehicle options expand, manufacturers must switch materials and colors **quickly**—but **traditional purge methods waste time and material**. ⏳ **Without a purge program:** - Material transitions take **30–60+ minutes** - More **wasted resin** leads to higher costs - Increased **scrap rates** result in lost revenue ⚡ **With an effective purge program:** ✔ **Changeovers completed in 5–15 minutes** ✔ **50%+ less material used per purge** ✔ **Minimal leftover contamination** → Faster, cleaner transitions 🔎 **Case Study:** A Tier 1 supplier reduced their **color change time from 42 minutes to 11 minutes**—saving **hundreds of hours per year** in production time. --- ## **4. Extending Equipment Lifespan & Efficiency** 💰 **A poorly maintained machine costs you money.** Injection molding machines must run **at peak efficiency** to stay competitive. But over time, residual plastic, colorant buildup, and degraded material can lead to: ❌ **Screw wear** → Higher maintenance costs ❌ **Carbon contamination** → Defects & scrap ❌ **Inconsistent cycles** → Slower production 🔧 **Purging prevents this.** ✅ **Regular purging keeps screws, barrels, and hot runners clean** ✅ **Reduces unplanned downtime & emergency maintenance** ✅ **Maintains processing consistency for tighter tolerances** 🔍 **Efficiency Tip:** Purging compounds designed for **hot runners** help prevent carbon contamination in **multi-cavity molds**, ensuring perfect part quality. --- ## **5. The REAL Cost of Purging: Cost-per-Purge vs. Cost-per-Pound** 📉 **Many molders try to cut costs by using regrind or virgin resin instead of a dedicated purging compound.** But this **false economy** leads to: 🚨 **3–5x more material needed per purge** 🚨 **Longer machine downtime** 🚨 **Higher scrap rates** **Cost Breakdown:** | Purging Method | Material Used | Changeover Time | Scrap Rate | Cost Impact | | --- | --- | --- | --- | --- | | **Regrind/Resin** | 3–5x more material | 30–60 min | High | Expensive in the long run | | **Asaclean® Purging Compounds** | Minimal usage | 5–15 min | Low | Maximizes efficiency & cost savings | 💡 **Example:** A manufacturer **saved $28,000 annually** by switching from regrind to Asaclean®—a 72% cost reduction in scrap and downtime. --- ## **Why Automotive Manufacturers Trust Asaclean®** 📌 **25+ years** of expertise in automotive molding 📌 **Industry-leading formulations** for thermoplastics 📌 **OEM-approved solutions** used by Tier 1 suppliers 📌 **44% average reduction in scrap & downtime** **The Bottom Line:** ✅ **Less waste, fewer rejects, faster changeovers** ✅ **Lower maintenance costs & improved machine lifespan** ✅ **Increased efficiency & profitability** 🔹 **Is Your Facility Running at Maximum Efficiency?** Don’t let inefficient purging hold you back. 💡 **Get expert guidance and a free purging consultation today!** [![](https://no-cache.hubspot.com/cta/default/468726/interactive-161630774182.png) ](https://www.asaclean.com/hs/cta/wi/redirect?encryptedPayload=AVxigLJmMvw74enDqB97%2FiICK%2Bo%2FCO34mS%2FkVd6N4p2mwme%2FwUK802hwLwXxRHQnfPWT3dpsFKp1qXM%2BcbpYHVp0ZMf4pjxtY4JxByPx%2F34cGUy0ngVAksAqmruc%2Fhf807WR6ljnmKUewpY%2Fu96kn0cdhvQjuDZ%2FwqgERJSWLPP7WxyMtuBQ6hu5sFO%2FtwT819sgjH0HmVEgFqAy4oxLDVGB%2F9TiL6f9EdJi1vasCHtZmsVoQNclTTvykd%2BC&webInteractiveContentId=161630774182&portalId=468726) ![Tom Hanvey](https://www.asaclean.com/hs-fs/hubfs/Tom%20Headshot.jpg?width=150&name=Tom%20Headshot.jpg) #### [ Tom Hanvey ](https://www.asaclean.com/blog/author/tom-hanvey) Tom Hanvey is the Associate Director of Marketing & Sustainability at Asahi Kasei Plastics North America.
